Question

<p>Identify the five compounds of H, N, and O described
below. For each compound, write a lewis structure that is
consistent with the information given.<br /><br />a.
All the compounds are electrolytes. Compounds C and D are ionic and
compound B is covalent.<br /><br />b. Nitrogen occurs
in its highest possible oxidation state in compounds A and C;
nitrogen occurs in its lowest possible oxidation state in compounds
C, D, and E. The formal charge on both nitrogens in compound C is
+1; the formal charge on the nitrogen in compound B is 0.<br
/><br />c. Compounds A and E exist in solution. Both
solutions give off gases. Commercially available concentrated
solutions of compound A are normally 16
<em>M</em>.&#160; The commercial, concentrated
solution of compound E is 15
<em>M</em>.</p>
<p>&#160;</p>
<p>d.&#160;Commercial solutions of compound E are labeled
with a misnomer that implies that a binary, gaseous compound of
nitrogen and hydrogen has reacted with water to produce ammonium
ions and hydroxide ions.&#160; Actually, this reaction occurs
to only a slight extent.</p>
<p>&#160;</p>
<p>e. Compound D is 43.7% N and 50.0% O by mass.&#160; If
compound D were a gas at STP, it would have a density of 2.86
g/L.</p>
<p>&#160;</p>
<p>f. A formula unit of compound C has one more oxygen than a
formula unit of compound D.&#160; Compounds C and A have one
ion in common when compound A is acting as a strong
electrolyte.</p>
<p>&#160;</p>
<p>g. Solutions of compound C are weakly acidic; solutions of
compound A are strongly acidic; solutions of compounds B and E are
basic.&#160; The titration of 0.726 g of compound B requires
21.98 mL of 1.000 <em>M</em> HCl for complete
neutralization.</p>
